BR-AE-08: For the Reverse charge category, the VAT breakdown's taxable amount…
What it means
For the Reverse charge category, the VAT breakdown's taxable amount (BT-116) does not equal the sum of reverse-charge line net amounts, plus charges, minus allowances.
How to fix it
Recompute the reverse-charge category's taxable amount from the lines, charges and allowances marked reverse charge, at the source. Arithmetic mismatch -- reported, never auto-repaired.
